[65.08] Utilizing solar sails for solar physics

Recently, there has been much interest in the use of solar
sail technology for advanced space mission concepts. We
present here some trajectories and orbits for a number of
potential solar missions. These missions utilize the power
of solar sails in a number of different ways, providing
unique capabilities in the study of the Sun.

The first mission concept is a solar polar mission using a
"parking orbit" above one of the solar poles, the second is
a multi-spacecraft mission designed to map out the
three-dimensional solar atmosphere using identical
spacecraft at different heliographic latitudes, and the
third is a STEREO slowdown mission designed to extend the
lifetime of the STEREO mission using small sails attached to
the STEREO payloads to slow down the rate of drift ahead and
behind the Earth.

Here, the first two payloads are assumed to be inert masses
with possible instrument and spacecraft packages to be
defined by the specific goals of any mission.
